Justice Department: Say ‘No’ to Google on Java Copyright Petition

The U.S. Justice Department has urged the Supreme Court to deny Google's latest petition to review rulings that the Alphabet subsidiary infringed on Oracle's copyrights to Java code -- rulings that could cost Google billions.

This petition keeps alive the nine-year legal struggle over 37 Java APIs Google used to develop its Android operating system, which Oracle has maintained were copyrighted, and for the violation of which Oracle is demanding $9 billion in damages. The courts have gone back and forth on the issues in this case, but eventually came down on the side of Oracle's claim.

Google filed a writ of certiorari with the Supreme Court earlier this year, asking for a review of the earlier judgment of the United States Court of Appeals for the Federal Circuit in this case.

"Above and beyond the broader implications for copyright law, this case warrants the Court's attention for its sheer practical importance," the petition reads. The ruling " ... threatens the prevailing approach to building computer software ... "

Google cited changing practices among software developers to support its petition. "Developers are not coding programs entirely from scratch," the company argued, "as they may have been in the early days of programming. Instead, new programs now incorporate and rely on preexisting interfaces to trigger certain functions, which saves the wasted effort of reinventing and retesting what came before."

In late September, the Solicitor General filed an amicus curiae brief to express the views of the United States on Google's petition. "Computer code can be used in transformative ways," it reads, "such as by excerpting it in a textbook to illustrate a coding technique. And lower courts have wrestled with issues, not presented here, about whether making temporary copies of existing code to 'reverse engineer' a system, in order to create compatible works that do not incorporate the pre-existing code, constitutes fair use ... . But here, petitioner took lines of code from a rival software platform to make a competing platform that is not interoperable with the Java platform."

"Petitioner copied 11,500 lines of computer code verbatim, as well as the complex structure and organization inherent in that code, in order to help its competing commercial product. The record demonstrates, moreover, that petitioner's unauthorized copying harmed the market for respondent's Java platform ... ."

"Petitioner identifies no sound basis for further review of the fair-use issue," the Justice Department concluded.

Oracle originally sued Google in 2010, and the search engine giant's argument that its use of the Java APIs was allowed under the fair use provisions of the federal copyright law, and therefore did not infringe on Oracle-owned copyrights, failed to persuade the court. "There is nothing fair about taking a copyrighted work verbatim and using it for the same purpose and function as the original in a competing platform," a panel of three Federal Circuit judges wrote in their opinion.

The Supremes are certainly free to consider Google's petition, but they have stayed out of the fight so far. We're surely approaching the conclusion of this seemingly immortal struggle, but given what it will cost the loser, I wouldn't bet on it.

Oracle Reviews the Java Rapid Release Cadence: So Far, So Good

One of the most-mentioned keynote topics at this year's Oracle OpenWorld-adjacent Code One 2019 conference, wrapping up this week in San Francisco, was the rapid release cadence for Java SE and the JDK, which Oracle announced in 2017 and launched in March of last year.

The rapid release cadence has proved to be one of those slap-the-forehead innovations that revivified the process of evolving the Java platform. Instead of allowing years to pass between releases and putting intense pressure on, well, every contributor in the community, to deliver and bet on big, fully formed enhancements, the new process runs on a cycle that calls for a feature release every six months, update releases every quarter, and a long-term support release every three years.

"That's fast enough to minimize the pain of waiting for the next [release] train," wrote Mark Reinhold, chief architect of Oracle's Java Platform Group, in the blog post in which he first proposed the faster cadence, "yet slow enough that we can still deliver each release at a high level of quality, preserving Java's key long-term values of compatibility, reliability, and thoughtful evolution."

JDK 10 was the first feature release of the new cycle; Java 11, which was released six months later, was the first long-term support (LTS) release. The next LTS release will be Java 17, scheduled September 2021. Java 13, which went GA this week, is not an LTS release, which means it will be obsoleted with the release of Java 14 in March, 2020.

And yet it seems people are still getting used to the idea, which I suppose underscores the depth of the change. Java Language Architect Brian Goetz reminded conference attendees during his Code One keynote to remember that the rapid release cadence imposed a truly fundamental change on a long-established process.

"A lot of people, including, quite honestly, us, were pretty skeptical at first," Goetz admitted. "It seemed inconceivable that we could turn a ship as big as Java that quickly. There were even fears that Java 10 and 11 might have no features at all. But looking back, it would be really hard to overstate what a significant change the rapid release cadence has been."

Among the benefits of the new cadence, he said, are the obvious: "We can deliver value more often, and you don't have to wait as long for any particular feature to come out." And the not-so-obvious: "It has brought about this fundamental change in how we design, plan, and deliver new features by lowering the cost of a feature missing the boat. Missing by six months is a whole lot different from missing by several years. [The faster release cadence] has drastically reduced our release-management overhead internally, which allows us to spend more energy on designing and building features and less energy on managing releases."

"And at the same time, having more releases has encouraged us to learn how to break down complex features into smaller ones, so we can deliver in phases," he added. "The results, which has sort of been an unexpected one, is that our feature pipeline has become richer than it has ever been. The whole thing has been one big virtuous circle."

Adapting to the faster release cadence has required the Java community to "recalibrate our expectations," Goetz said, "about what constitutes something worth upgrading.

"In the old world, when we had these big releases every few years, and those big releases tended to have big features, like Generics and Lambda's, there was already plenty of motivation to upgrade. The reality now is, we're not going to be seeing a lot of those big features in the future. And that's not because we're not innovating. It's because those big features are going to get broken up into smaller features and delivered in phases. There's just as much innovation going on -- perhaps more -- but it's going to be spread out over a large number of smaller deliveries."

During his Code One presentation, Georges Saab, VP of Oracle's Java Platform Group and OpenJDK chairperson, also reminisced about the launch of the new release cadence into skeptical waters.

"Many folks were excited about the faster cadence," he said. "Many folks were apprehensive about it. And there are a lot of people who were actually both ... . Some of the most apprehensive people were on my team at Oracle working on Java! When we floated the idea of six months releases, they really thought I was crazy. They said because of the Java Community Process (JCP), through which the Java platform evolves, it just takes too long. This process requires that there be a specification, a reference implementation, and a certified compatible testing kit ... .But I had faith that, like us, many in the JCP Executive Committee (EC) wanted to see a faster and more gradual evolution of Java."

And then he brought out the big guns: Bruno Souza, leader of the Brazilian Java community known as SouJava, and Gil Tene, CTO and co-founder of Azul Systems, maker of the Zing Java runtime, among other products, the only vendor focused exclusively on Java and the JVM. Both are JCP EC members. (The lively Souza wore a cape that has yet to be explained.)

Tene said he and the other EC members were very skeptical when they first heard about the rapid release cadence for Java. "The benefits of the faster cadence were obvious," he said, "if it could be done, but the shortest we had ever done a spec process at the time was 10 months."

The challenge for the EC, Souza said, came down to one question: "How do we do a fast open-source model and at the same time retain the stability Java has."

"As we moved to a fast cadence process," he said, "we had to take a very critical look at what [we were] doing a the JCP. And so we removed everything that prevented us from going to an open-source-friendly-early-release-often model, but at the same time we kept and improved on everything that guarantees the stability, long term, of the specification that is so important to the Java community."

Tene agreed that the rapid release cadence was a welcome idea that had to prove itself to the EC in specific ways. The JCP is where the specification, the reference implementation, and the Technology Compatibility Kit (TCK) come together, he said.

"The reason the Java ecosystem has such a rich set of code and libraries -- the reason Maven Central works on all the differentiated cases out there -- is because we do this work, because the specification is specific, and because the TCK lets us verify that all these implementations really will run the same way," he said.

How did it work out?

"We think it's worked out great," Tene said.

Q&A: Eclipse Foundation's Milinkovich on the Road to Jakarta EE 8

The Eclipse Foundation today announced the released the first Jakarta EE specification, almost exactly two years after Oracle declared its intention to transfer the responsibility for enterprise Java to that open source standards organization.

Two years seems like a long time, but the Foundation's executive director, Mike Milinkovich, says that's just how long it took to get the specs right. I talked with Milinkovich last week about the road to the Eclipse Jakarta EE 8 release.

I've been calling the Foundation's adoption of enterprise Java and the development of a standards process for it "the road to Jakarta EE 8." I'm just assuming it was a bumpy one, but how was it really?
When we started down this road, we always said that our first order of business would be to ship a set of specs that were exactly the same as Java EE 8, so we had that baseline. When we first started saying that, it just seemed like a good, solid, conservative thing to do to make sure that we got it done. It turns out that we were really darned lucky we did it that way. It would have been borderline crazy to do anything else.

How do you mean?
The first time you run through a very large and complex process you inevitably run into unforeseen circumstances. In this release cycle, we took exactly the same specs and ran them through a new process, but we changed a few things -- the TCKs are now open source, the specifications are under a new license, there's no more reference implementation, there are multiple compatible implementations -- but those are all process changes. We're not delivering new technology to developers yet. But every one of those process changes, introduced somewhere along the way, had its own little bit of complexity that you just couldn't foresee.

Seems like it was a ton of work.
We rewrote our IP policy -- twice -- we developed a spec process from scratch, and we updated all of our contribution agreements and got tens of thousands of people to resign them. So, yeah, you could say that.

And, as you've often said, you weren't doing this alone.
I can't stress enough how many good people pitched in and worked hard to make this possible. Oracle, Red Hat, IBM, Tomitribe, Payara, Fujitsu, to name a few. It was a community effort to get this thing out the door.

There are a lot of people with skin in this game.
Well, Java is old technology -- more than 20 years old -- but it's a multi-billion-dollar ecosystem, and there are millions of developers who have skills with this platform. Basically, everything we're doing right now is about establishing a baseline that's going to allow us to re-invigorate this platform for the next 20 years.

Why is re-invigorating the enterprise Java platform so important?
Enterprises want to see that there's a way to modernize their applications, in many cases, to take what they have now inside the corporate firewall to the cloud. They want to leverage this new infrastructure model with existing applications that are known to solve their business problems. Also, enterprises have thousands of developers with skills on this platform -- people who understand the businesses they work for. We need to demonstrate to those people that the technology platform they have skills in is still relevant and will keep them gainfully employed for the next 20 years. And then there's the need to attract young talent to a platform by making it exciting again.

So, all the work you've done on this release is essentially about setting the stage, so to speak, for innovations to come?
We had to get this part right. Large companies are making big bets on their product plans and this technology, so we focused on doing something concrete that would reassure the market and the community.

And no small part of your challenge was the fact that the Eclipse Foundation was not a specification organization when you accepted the stewardship of enterprise Java.
That's right! We were creating a brand-new specification process from a blank piece of paper, rewriting our IP policy to handle patents correctly, which is very different from how you do things in open source. Luckily, we were doing all this with smart engineers, experienced standards people, and lots of opinionated lawyers from software companies around the world.

Talk about "Incremental versus Big Bang."
What we ended up with in our negotiations with Oracle, remember, is that every time we add a new API, or we make a change to an existing API, that has to happen in the Jakarta namespace. The javax package names cannot be evolved by the Jakarta EE community. So, do we switch everything from javax.* to jakarta.* all at once -- that's the Big Bang -- or do we make the change a little bit at a time, as needed -- in other words, incrementally? In other words, do we rip the band aid off, or do we deal with these compatibility issues with every single release for the next 20 years?

Sound like you favor the Big Bang.
That's my personal preference. Let's just get it over with. But there are valid arguments for an incremental approach. Ultimately, this is about what's best for the customers, what's best for the ecosystem. The vendors have varying opinions on this, based on what they think their customers perspective would be. But what a lot of it really boils down to is, to what degree can we offer a reasonable set of technical solutions to the backwards compatibility problem? This is a really big decision that has to be made over the next couple of months.

The decision to move enterprise Java to the Foundation elicited a largely positively reaction from the community. Did you get any significant pushback?
Java developers are not shy, and they always let us know what they think. But they were onboard for this.

Were you surprised at how long it took to get here?
I was a little bit. I'm an optimist by nature, and I had a very clear idea from the beginning of where I wanted this end up. And we got very close to what I hoped for. But it takes a long time to pull a thing like this together. I remember someone saying, "There's no way you're going to get this done in less than a year." And they were right, of course. You can't change legal documents willy-nilly, and you have to take the time to explain to the community -- thousands of people around the world -- what the changes are and why we're making them. But I believe it was time well spent.

Eclipse Foundation Gears Up for Enterprise Java Release with JakartaOne Live Stream

The Eclipse Foundation is gearing up for the Sept. 10 release of Jakarta EE 8, the first version of the enterprise Java platform under the Foundation's stewardship, with, among other things, a livestream event.

The JakartaOne Livestream is a one-day virtual conference aimed at developers and technical business leaders interested in "the current state and future of Jakarta EE and related technologies," with a focus on developing cloud native Java applications.

Perhaps named with a nostalgic nod to the venerable JavaOne conference, which is now CodeOne, (I'd like to think so, anyway), JakartaOne is scheduled for the same day as the Jakarta EE 8 release. The event features sessions and keynotes organized by an all-star program committee that includes Reza Rahman, principal program manager for Java on Azure at Microsoft, and one of the founders of the Java EE Guardians (and a personal fav speaker); veteran Java SE/EE developer, Java Champion, and popular YouTube educator Adam Bien; Arun Gupta, principal technologist at Amazon Web Services and the guy responsible for the Cloud Native Computing Foundation (CNCF) strategy within AWS (and founder of the Devoxx4Kids chapter in the US); Ivar Grimstad, Java Champion and PMC lead for the Eclipse Enterprise for Java Project (EE4J), the top-level project for Jakarta EE within Eclipse; Josh Juneau, developer, system analyst, and a fav blogger and author; and Tanja Obradovic, who joined Eclipse Foundation as Jakarta EE Program Manager June 2018.

Juneau, Grimstad, Bien, and Rahman will be presenting at the event, which will include keynotes by the Eclipse Foundation's executive director, Mike Milinkovich, and the Father of Java, James Gosling. There's also an industry keynote featuring vendors with lots of skin in the enterprise Java game, such as IBM, Oracle, Payara, Tomitribe and Fujitsu. Payara CEO Steve Millidge will be presenting, as will Tomitribe founder David Blevins, JCP star specification lead Dmitry Kornilov, and Java EE Guardians Arjan Tijms and Markus Karg, among others

Session topics range from Jakarta EE 8 features to a state-of-the-union for MicroProfile, Quarkus to Helidon. And the cloud, of course. Among the key findings of an Eclipse Foundation enterprise developer survey, published earlier this year: "The future of the Java ecosystem and Jakarta EE is increasingly driven by new cloud workloads and capabilities."

"Java continues to dominate as the language of choice for organizations deploying applications in production environments," Milinkovich at the time, "and this latest survey shows the same level of support as our 2018 survey. What's most interesting is to see the acceleration in the adoption of Java in new cloud native architectures. Clearly the future of Jakarta EE is cloud native."

In fact, this free, virtual, time-zone spanning conference was developed, in part, as a reaction to what Obradovic described in a blog post as "huge interest" in the Cloud Native track at the October EclipseCon Europe 2019.

Enterprise Java jocks -- or anyone, really -- can register now for what many (including me) consider to be a must-attend event.

Jelastic Extends Support for Java Runtimes

Jelastic, the Java-focused cloud hosting platform provider, today announced new support for several Java runtimes, including AdoptOpenJDK, Liberica, Zulu, Corretto, OpenJ9 and GraalVM.

Jelastic built the runtimes as certified and secure container-based images with pre-configured automatic vertical scaling, explained Tetiana Fydorenchyk, Jelastic’s VP of marketing, in a blog post. The company made them available across all existing production platform installations, and Jelastic PaaS users are now able to choose the type and version of the OpenJDK distribution while creating the environment or easily change it by redeploying containers afterward.

The Palo Alto, Calif.-based Jelastic (short for Java Elastic), which was founded in 2010 by Hivetext, a Zhytomyr, Ukraine-based start-up focused on Java application development in the cloud, bills itself as the only cloud company whose underlying platform is Java. Originally a Java-based Platform-as-a-Service provider, the company has been evolving a Platform-as-Infrastructure strategy that combines PaaS with Infrastructure-as-a-Service. Jelastic’s unlimited PaaS and container-based IaaS platform is designed to allow developers to deploy Java, PHP, Ruby, Node.js, Python, and .NET enterprise apps for private, public or hybrid cloud.

Although its platform is now multilingual, the company maintains “a major focus on Java,” the company has said.

“We love organizations like Jelastic, who, like us, were created out of a community need by developers for developers,” said Martijn Verburg, director at AdoptOpenJDK, CEO of jClarity, co-organizer of the London JUG, and a member of the Java Community Process (JCP) Executive Committee, in a statement. “With well over 50 Million downloads, AdoptOpenJDK has become the defacto hub for the community to collaborate on, and we’re very happy to be added as a choice to the awesome Java hosting company PaaS that is Jelastic!”

AdoptOpenJDK uses infrastructure, build, and test scripts to produce prebuilt binaries from OpenJDK class libraries and a choice of either the OpenJDK HotSpot or Eclipse OpenJ9 VM. It’s a free and open source implementation supported by a range of companies, from IBM and Microsoft to GoDaddy and Pivotal.

Azul Systems’ Zulu implementation of the Java Standard Edition (SE) specification that contains all the Java components needed to build and run Java SE apps. Azul’s CTO Gil Tene, said his company was happy to see “a wide set of OpenJDK variants added to the Jelastic PaaS that provides customers with elasticity in both scale and runtime choice.”

Amazon Corretto is a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit (OpenJDK) certified as compatible with the Java SE standard. It comes with long-term support that includes performance enhancements and security fixes, and it allows developers it build and run Java applications on operating systems such as Amazon Linux 2, Windows, and macOS. Amazon uses it internally.

Eclipse OpenJ9 is an open source JVM optimized for small footprint, fast startup, and high throughput. It can be built as a component of OpenJDK v8 and later, and prebuilt binaries available at the AdoptOpenJDK project for Linux and Windows. Unsurprisingly, Dan Heidinga, Eclipse OpenJ9 project lead, was pleased to hear about the support. “Jelastic user focus comes across loud and clear in the broad choice of OpenJDK variants they provide on their PaaS,” he said in a statement.

Liberica is a certified, Java SE 12-compliant distribution of OpenJDK 12. It’s a 100 percent open source Java implementation built from OpenJDK by BellSoft.

The GraalVM is an extension of the JVM designed to run applications written in a range of languages, including JavaScript, Python, Ruby, and R; JVM-based languages, such as Java, Scala, and Kotlin; and LLVM-based languages, such as C and C++. Graal is the Java-based JIT compiler (JEP 317) that is the basis of the experimental AOT compiler introduced in JDK 9.

“We are glad to see Jelastic join the growing number of cloud services and open source projects that are adopting GraalVM,” said Eric Sedlar, VP and technical director at Oracle Labs. “GraalVM provides zero overhead interoperability between programming languages allowing developers to write polyglot applications and select the best language for your task.”

Proposal to Migrate JDK from Mercurial to Git Gets a JEP

Call it "A Tale of Two Repositories."

Mercurial is a free, cross-platform, distributed version-control system (SVM), and current host of the source files and change histories of most JDK projects since 2008. Git is the free, cross-platform, distributed version-control system that is almost certain to become the new home of those repositories.

It has been almost exactly one year since the launch of Project Skara, an investigation of alternative source-code management (SCM) systems and code review options for the JDK -- and in particular, whether Git might not be a better option than Mercurial. Sponsored by the Build Infrastructure Group and led by Joseph Darcy, a member of the Technical Staff at Oracle, the project sparked a serious discussion in the Java community about SCM options for OpenJDK.

For at least two Java jocks (and a whole lot more), that discussion turned into action last week, when Darcy and his colleague on Oracle's Technical Staff, Erik Duveblad, proposed JEP 357, the goal of which is to "Migrate all single-repository OpenJDK Projects from Mercurial to Git."

The list of specific goals of JEP 357 includes:

  • Migrate all single-repository OpenJDK Projects from Mercurial to Git
  • Preserve all version control history, including tags
  • Reformat commit messages according to Git best practices
  • Port the jcheck, webrev, and defpath tools to Git
  • Create a tool to translate between Mercurial and Git hashes

The JEP's authors also included a list of things they will not do:

  • We will not migrate multi-repository OpenJDK Projects, such as the JDK 8 Updates Project. Those Projects can migrate to Git if and when they consolidate into a single repository.
  • We will not change the bug system from JBS.
  • We will not address the question of whether OpenJDK Git repositories will be self-hosted or hosted by an external provider. That issue will be the topic of a future JEP.
  • We will not propose changes to the current JDK development process, though this JEP does enable such changes.

The bottom line for proponents of this move is that Git has the potential to handle larger projects. In the prototypes initially developed via the Skara project, converted repositories showed "a significant reduction in the size of the version control metadata," the JEP authors reported. In one example cited, the .git directory of the jdk/jdk repository, which is approximately 300 MB with Git is about 1.2 GB with Mercurial, depending on the Mercurial version being used.

"The reduction in metadata preserves local disk space and reduces clone times," they wrote, "since fewer bits have to go over the wire. Git also features shallow clones that only clone parts of the history, resulting in even less metadata for those users who do not need the entire history."

And then there's the bulging toolbox Git provides: text editors with Git integration (native and plugins), including Emacs, Vim, VS Code, and Atom; almost all IDEs ship with Git integration out of the box, including IntelliJ, Eclipse, NetBeans, and Visual Studio; and multiple desktop clients are available for local interaction with Git repositories.

The group working on JEP 357 has already prototyped a program to convert a Mercurial repository to a Git repository. The structures of commit messages for both Mercurial and Git jdk/jdk repositories are shown on the JEP page. The group has also prototyped backward compatible ports of several Mercurial tools.

Examples of converted repositories are available at https://github.com/openjdk/.

Rebooting OpenJDK Mobile

Is it time to "reboot" the OpenJDK Mobile Project, which focused on porting the JDK to iOS, Android, and the now deceased Windows Mobile? Johan Vox, co-founder of Gluon, a Belgium-based mobile solutions, and a Java Champion, thinks so.

Vox made his case recently for restarting public work on the fallow project on the mobile-dev mailing list. "After a long time, it is a good moment now to restart the public work in the OpenJDK Mobile project," he wrote.

"In the past, we had a repository with code based on OpenJDK 9 that allows [us] to build the class libraries (including native code) and one or more VMs for Android and iOS," he explained. "While this works, we still have the limitation on iOS, where dynamic code is not allowed, hence a JIT is not an option. The Zero VM works there (interpreter mode) but [it] is slow."

Vox's idea is to use the GraalVM AOT compiler to compile the code at build time. The compiled Java code could be linked with native libraries compiled for the target OS and create executables. Most of the VM functionality is provided by a very small set of files in SubstrateVM, he explained, which are linked to via the GraalVM native image.

"We already did this for iOS, based on Java 11," he wrote, referring to the June release by his company of Gluon Client plugins that support Java and JavaFX on iOS devices. "The [difference] to the upstream code is remarkably small."

The Gluon Client plugins, currently in beta, offer configurations for running Java 11+ and Java FX apps on iOS devices or the iPhone simulator. They're designed to allow developers to create iOS and Android apps in Java. Gluon Mobile provides UI control for the client application, handles communication with the server-side cloud and third-party services, and abstracts the platform-specific APIs. Gluon Client tools can generate a native executable for iOS devices.

The OpenJDK Mobile Project was originally set up to manage two different repositories, each with a different set of integration rules. The mobile/jdk9 forest was allowed to contain only the OpenJDK officially approved changeset that had been reviewed as if it were going to be immediately integrated into JDK 9. The mobile/dev repository was designed to be used for integration of features that were not approved for JDK 9 integration, early prototypes, or sharing of early features not yet ready for integration into mobile/jdk9.

For his part, Voss plans to use Project Skara, an alternative SCM and code review tool, to create a "synchronized fork" of the OpenJDK master and to push the changes required to build the native libs for the core libraries.

"Ultimately, it would be ideal if all required changes can go upstream, he wrote. "At this moment, this is iOS only, but there are no showstoppers to do this for Android as well. The architectures are pretty similar."

Eclipse SimRel-2019-06 Now Available

The Eclipse Foundation announced the latest of its stepped-up simultaneous project releases last week. SimRel-2019-06, its second quarterly release, comprises 76 projects, including the latest Eclipse IDE. Actually, the entire list is simply considered part of the Eclipse IDE 2019-06 release train.

Although this new fast-paced release schedule has been largely welcomed by the community, keeping up has taken some getting used to for more than a few. If you're among those who find themselves scrambling to stay abreast of the changes, check out the Foundation's simultaneous release schedule.

Among the new and noteworthy in this release (according to the Foundation) are:

  • Eclipse Buildship: Eclipse Plug-ins for Gradle 3.1.0 Eclipse Buildship is a collection of Eclipse plug-ins that provide support for building software using Gradle. Buildship aims to provide a deep integration, and to make the Eclipse IDE more powerful by allowing the user to do more from within the IDE.

    Since Gradle 5.4, projects have been able to declare an arbitrary set of tasks in the eclipse.synchronizationTasks configuration. Once configured, Gradle will automatically execute those tasks every time the user synchronizes workspace with the build.

  • Eclipse Business Intelligence and Reporting Tools (BIRT) 4.7.0 Eclipse BIRT is an open source Eclipse-based reporting system that integrates with Java/enterprise Java applications to produce "compelling reports." It's used to create data visualizations and reports that can be embedded into rich client and Web applications.

  • Eclipse Business Process Model and Notation (BPMN2) 1.5.0 Eclipse BPMN2 is an open source component of the Model Development Tools (MDT) subproject to provide a metamodel implementation based on the forthcoming Business Process Model and Notation (BPMN) 2.0 OMG specification. The goal of this release is to synchronize with Eclipse Photon, a past version of Eclipse. No new major enhancement are currently planned.

  • Eclipse C/C++ Development Tooling (CDT) 9.8.0 The Eclipse CDT Project provides a fully functional C and C++ IDE based on the Eclipse platform. Features include: support for project creation and managed build for various toolchains, standard make build, source navigation, various source knowledge tools, such as type hierarchy, call graph, include browser, macro definition browser, code editor with syntax highlighting, folding and hyperlink navigation, source code refactoring and code generation, visual debugging tools, including memory, registers, and disassembly viewers.

  • Eclipse CDO Model Repository 4.7.0 The Eclipse CDO (Connected Data Objects) Model Repository is a distributed shared model framework for EMF models and meta models. CDO is also a model runtime environment with a focus on orthogonal aspects, such as model scalability, transactionality, persistence, distribution, and queries.

    CDO has a 3-tier architecture supporting EMF-based client applications, featuring a central model repository server and leveraging different types of pluggable data storage back-ends like relational databases, object databases and file systems. The default client/server communication protocol is implemented with the Net4j Signalling Platform.

  • Eclipse Collections 9.2.0 Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set, and Map implementations with a rich API, additional types not found in the JDK, such as Bags, Multimaps, and a set of utility classes that work with any JDK compatible Collections, Arrays, Maps, or Strings. The iteration protocol was inspired by the Smalltalk collection framework. Eclipse Collections originated as an open source project on GitHub called GS Collections. This is also the Photon release of Eclipse Collections project.

  • Eclipse Dynamic Languages Toolkit 5.11 The Eclipse Dynamic Languages Toolkit (DLTK) is a tool for vendors, researchers, and end-users who rely on dynamic languages. DLTK comprises a set of extensible frameworks designed to reduce the complexity of building full featured development environments for dynamic languages, such as PHP and Perl. Besides a set of frameworks, DLTK provides exemplary Tcl, Ruby, and Python IDEs ready to use out of the box.

Oracle to Eclipse Hand-Off: The Enterprise Java Community Moves Forward

It's been about a month since Mike Milinkovich, executive director of the Eclipse Foundation, explained in a blog post the status of negotiations between Eclipse and Oracle on the final details of the enterprise Java handoff agreement. The last bone of contention was the use of the javax* package namespace "in the evolution" of Jakarta EE specifications, and the use of Java trademarks in the Java EE spec, but the two organizations got past it.

"[F]ollowing many months of good-faith negotiations, the Eclipse Foundation and Oracle have been unable to agree on terms of an agreement for the Eclipse Foundation community to modify the javax* package namespace or to use the Java trademarks currently used in Java EE specifications," Milinkovich wrote. "Instead, Eclipse and Oracle have agreed that the javax* package namespace cannot be evolved by the Jakarta EE community. As well, Java trademarks such as the existing specification names cannot be used by Jakarta EE specifications."

He added that the details of the talks would remain under wraps: "Because of the complexity and confidential nature of our negotiations, the Eclipse Foundation and Oracle have also agreed that we will not attempt to characterize here what has resulted in this outcome. It is the best outcome we could mutually achieve for the community."

Even one of the most vocal critics of Oracle's intractability on these two issues, the Java EE Guardians, seems ready to move on. The group of volunteers who joined forces in 2016 to support enterprise Java, then in the hands of a seemingly indifferent Oracle, declared in a recent blog post their "great excitement" about the final agreement between Big O and the Eclipse community. But that excitement was tempered with a splash of caution.

"One of the critical decisions that needs to be made prior to moving forward is how to proceed with the transition from the javax* namespace," they advised. "The Java EE Guardians agree with the consensus of many in the community, as there is a broad desire to move everything to the jakarta* namespace at once, rather than taking an incremental approach. The Java EE Guardians encourage the community and the Eclipse Foundation to focus on getting a clear consensus about this quickly so that Jakarta EE can confidently evolve with no more delays."

"The truth is, we're thrilled about this agreement," Dennis R. Gesker told me. "I know I'm commenting from out in the cheap seats, but here in my shop, we're like, wow, things have gone from glacially slow to superfast. And that's a good thing."

Gesker is chief technology officer at Alamon Inc., in Kalispell, Mo., and a member of the Guardians. And his "cheap seats" are in a real-world daily work environment.

"We see [the agreement] as a great opportunity to start building cohesion across the ecosystem," Gesker said. "Not to cast aspersions, but we've got an honest broker inside Eclipse now to start moving things along really fast, and then start bringing in some folks who have spun out into other projects. This is a chance to say, come on in and bring your ideas with you. Me in particular, but my guys as well: we're hoping they take a Big Bang approach: rename it, refactor, move on -- and deal with compatibility issues as they arrive."

Going forward, the enterprise Java community will have to steer clear of the "Java" trademark, and the evolution of the APIs cannot take place under the javax* package.

"However," the Guardians noted, "Jakarta EE will be able to use the Java EE APIs and javax* package as-is and be able to evolve the technology forward under the jakarta* package. This will provide a path forward to further evolve widely relied upon Java EE APIs such as Servlet, JPA, JAX-RS, WebSocket, JMS and so many others. It can also be objectively said the transition from Java EE to Jakarta EE represents one the largest and perhaps most significant technology stewardship transfers ever attempted. This includes not just the agreement but the source code transfer of the Java EE compatibility test kit (TCK) as well as the reference implementation GlassFish.

"This is not a big deal for us," Gesker said, "for the day to day, guys, but I fully appreciate that the folks who have been hardcore promoters of Java EE for so long might not be that happy. I get why they might want to hold onto javax. Programmers have tools they like, and they can be really passionate about them. I mean, there's a flareup in my office every couple of weeks about who's using the best IDE! But I want to say, hold on, we're going to get it together. A lot of these growing pains are going to go away, and we're all going to become more effective and efficient."
